1. Be able to sort by date approved for FIFO type processing (it is impossible to determine which was first in so you can process first right now).
2. Be able to sort the list by creator. Why: When trying to approve invoices, each biller has a style. It would be so much easier to be able to confirm all invoices created by a single person. This way if there are issues (or you know that person is a rock star) you can quickly approve/reject as needed. It helps if you need to have further communications with that individual to be able to talk to them about all the issues at once rather than an email here and there.
